Abstract
>In the framework of the relativistic molecular dynamics approach (RQMD) we study pion and kaon production in the reactions p + Be, p + Au and Si + Au at a beam energy of 14.5 A GeV. In general we find good agreement for various particle yields and their momentum distributions comparing our results with recent experimental data taken at the AGS. In case of the gold target most of the primarily produced particles leave the reaction zone only after multiple interactions with the surrounding medium. For central Si on Au collisions meson and baryon resonance annihilation leads to strong strangeness enrichment. We predict that in effect of the meson cascading roughly half of the final pions are products from delta decays. This can be checked experimentally because of their characteristic momentum distribution.
